Reference to type 'IAuthorizationFilter' claims it is defined in 'Hangfire.Core', but it could not be found

Seems like `IAuthorizationFilter` is gone, but `BasicAuthAuthorizationFilter` still tries to implement it.

Packages used:
```xml

```

Start by reproducing the compiler error with the listed Hangfire.AspNetCore, Hangfire.Core, and Hangfire.Dashboard.Authorization package references. Inspect BasicAuthAuthorizationFilter and the Hangfire.Core 1.7.9 API to verify whether IAuthorizationFilter is available; done means the package combination builds successfully or the incompatibility is clearly identified.
